Since the minimum kernel version for use with glibc is 3.2, the glibc wrapper for this syscall can no longer usefully be called. This patch makes it into a compat symbol, not provided at all for static linking or new ports. (It was already the case that there was no header declaration of this function.) Tested for x86_64. 2018-05-18 Joseph Myers * sysdeps/unix/sysv/linux/syscalls.list (nfsservctl): Make into a compat symbol, disabled for minimum symbol version GLIBC_2.28 and later. diff --git a/NEWS b/NEWS index 4899a0a..bade9e4 100644 --- a/NEWS +++ b/NEWS @@ -69,6 +69,11 @@ Deprecated and removed features, and other changes affecting compatibility: binaries; the headers and have been removed.
